Sliding bearing split beam and large prefabricated trough plate assembly type subway station structure and construction method
The invention discloses a sliding bearing split beam and large prefabricated trough plate assembly type subway station structure and a construction method, a mixed construction scheme of cast-in-place of a bearing structure, prefabrication of a large-area floor structure and superimposed assembly is adopted, the integrity and reliability of a structure main body are guaranteed, the overall high prefabrication assembly rate is also guaranteed, and the construction cost is reduced. Support and formwork projects can be greatly reduced, and construction efficiency and environmental benefits can be improved; meanwhile, the large prefabricated trough plate overlapping assembly technology is adopted, the assembly efficiency can be improved, the connecting structure is simplified, material consumption and labor hour consumption are reduced, the connecting integrity is guaranteed, and compared with a large double-T plate, the problem that normal steel bars at the bottom of an overlapping floor slab are difficult to arrange is solved; besides, the split beam technology is adopted, the problem that shock insulation connection or sliding connection between a traditional integrated beam and a vertical component (such as a column and a wall) is not convenient to achieve is solved, and the problem of structural damage caused by insufficient shock deformation resistance of a middle column of an underground structure is ingeniously solved.
本发明公开了一种滑动支承分体梁与大型预制槽板装配式地铁车站结构及施工方法，采用承重结构现浇、大面积楼盖结构预制并叠合装配的混合施工方案，既保证了结构主体的整体性和可靠性，又保证了总体较高的预制装配率，能够大幅度减少支架和模板工程，能够提高施工效率和环境效益；同时，采用大型预制槽板叠合装配技术，能够提高装配效率、简化连接构造与材料及工时消耗、保证连接整体性，与大型双T板相比，本发明解决了叠合楼板板底正钢筋的布置困难问题；另外，采用分体梁技术，解决了传统一体梁与竖向构件(如柱、墙)之间不便于实现隔震连接或滑动连接的难题，巧妙解决了地下结构的中柱抗震变形能力不足所带来的结构破坏问题。
